Fail to open Local group policy
Go to C:\Windows\System32\GroupPolicy\Machine In this Machine folder there is a Script folder and the Registry.pol file. Rename Registry.pol in Registry.bak and that should do it. You may need to restart your computer for this but should end your troubles. (ref. https://www.sevenforums.com/general-discussion/76437-fail-open-local-group-policy.html)
